Apple CEO Tim Cook has confirmed that the company’s design supremo Jony Ive is indeed working on overhauling iOS 7 for launch at WWDC in June.

Speaking with AllThingsD, Cook revealed that Ive was “really key” to the development of the new iPhone and iPad operating system. He also reiterated is opinion of the English designer’s talents, calling him “absolutely incredible.”

Whilst Cook wouldn’t be drawn on the rumours surrounding the supposed iOS redesign, which include the idea that it will be much flatter and more abstract than the current iteration, Cook did confirm that it would be on show at Apple’s Worldwide Developer Conference being held on June 10.

Late last year, iOS chief Scott Forstall was ousted from Apple and hardware design head Jony Ive was given the expanded responsibility of overseeing Apple’s software output.

According to Cook, his Apple team realised that “Jony had contributed significantly to the look and feel of Apple over many many years and could do that for our software as well.”

It’s been widely reported for some time that Ive is not a fan of Apple’s skeuomorphic approach to software, in which its operating systems and apps are made to resemble real world equivalents. As such, it’s believed that iOS 7 will be “black, white and flat all over,” and may even resemble Windows Phone.
